Converting from a Normal
Curve to the z-Distribution

In order to utilize the table, it is necessary to convert the information
of any given Normal Curve to the Standard Normal Curve,
= 0;
s = 1. The table is entered with
the value z (the converted X value), and gives the cumulated area.
The equation for z is as follows:

Note that z is dependent on the population constants' mean and standard
deviation. In essence, z is the deviation of x from the Mean measured
in units of Standard Deviation. The same equation can be used for any
value of mu and theta of a population that follows the Normal Curve.
